4. Tom Hanks and Jim Hanks strike again.
Tom Hanks is not a big fan of running and Forrest runs a lot. Guess who got the role of running double? Jim Hanks, his brother! Talk about nepotism! As it is with many of Tom’s roles, his brother, Jim, acted as his double, filling in for re-shoots and stand-in purposes. These two look so much alike, it is near impossible to tell them apart in landscape, non-speaking shots.
